THE UK should reassess its defence presence in Scotland in light of new threats in the most northerly part of the globe, a committee of MPs has recommended.

The Scottish Affairs Committee also said a strategy for protecting offshore infrastructure is needed in the wake of the Nord Stream sabotage.

After conducting an inquiry on defence in Scotland, the cross-party committee called for clarity on how the military presence could be scaled up in response to potential future threats in the Arctic and the strategically important Greenland-Iceland-UK gap (GIUK).

As well as an increased Russian presence, China is taking a growing interest in Arctic politics and climate change is leading to new trade routes opening in the High North, which is loosely defined as the Arctic region and the seas surrounding it, including part of the North Atlantic.

Evidence from the Human Security Centre stated the RAF had too few Poseidon maritime patrol jets and Wedgetail early warning aircraft to provide a persistent presence.

Andrew Dorman, a professor of international security at King’s College London, told the MPs the RAF would require more Typhoon and F-35B fighters if there were a serious escalation in the region. The Faslane naval base’s role in policing the GIUK gap was said to be “critical”.

The committee is chaired by the SNP’s Pete Wishart, whose party wants the removal of the Trident nuclear deterrent from an independent Scotland. However, the report recognised there would be serious implications for the region if nuclear submarines were removed.

It said: “While not all members of the committee support this view (of maintaining Trident), we do recognise the serious implications for the UK and Nato should the nuclear fleet ever be removed from Faslane.”

The report continued: “The UK Government told us that repair of subsea cables was a matter for the cables’ commercial owners; we are concerned that the UK Government did not have more to say about how such important infrastructure could be repaired in the event of sabotage or failure.

“The UK Government should produce and publish a strategy for protecting offshore infrastructure.”

Wishart said Scotland had a “fundamental” role in the defence of the region: “During our inquiry, we heard widespread agreement that the Arctic is of growing strategic importance and maintaining a well-maintained and resourced military capability is essential to meet the UK’s defence interests.

“Because of its geography Scotland is home to a number of the UK’s strategic military assets and in our report we call on the UK Government to look at how the defence presence in Scotland could be scaled up if required to meet future threats. We are also calling for a review of the UK’s cold weather capabilities.

“We further looked at the opportunities and threats that may emerge because of climate change in the Arctic and the High North.

“Emerging trade routes and the responsibility of protecting offshore and subsea infrastructure are likely to become emerging priorities in a fast-changing environment.”
